| Question : | error: conflicting types for `XML_FEATURE_UNICODE' | |
| | Answer : | When installing PHP 4.4.0 on Slackware 10.2 using the following configure options
./configure --prefix=/usr/local/apache/php --with-config-file-path=/usr/local/lib --enable-xslt --with-xslt-sablot --with-mysql=/usr/local/mysql --enable-track-vars --enable-bcmath --enable-ftp --with-gd --enable-gd-native-tt --with-xpm-dir --with-png-dir --with-jpeg-dir --with-dom=/usr/local --with-zlib-dir --enable-trans-sid --with-mcrypt --with-mhash --with-curl --with-openssl --with-pspell --enable-wddx --enable-memory-limit --with-apxs=/usr/local/apache/bin/apxs
We got the following error
In file included from /usr/src/workspace/php-4.4.0/ext/wddx/php_wddx.h:26,
from main/internal_functions.c:50:
/usr/src/workspace/php-4.4.0/ext/xml/expat/expat.h:894: error: conflicting types for `XML_FEATURE_UNICODE'
/usr/include/libxml2/libxml/parser.h:1196: error: previous declaration of `XML_FEATURE_UNICODE'
make: *** [main/internal_functions.lo] Error 1
Using google it seemed a lot of people had the same problem, finally we tracked the problem down to libxml2 version libxml2-2.6.21.
This is the current version supplied with Slackware 10.2, so we built a new package based on libxml2-2.6.22.
Installed and re-ran the make for PHP and it compiled from source with no problems.
Make sure you un-install the previous version, the full package list from version 2.6.21 are listed below :-
